Possible Aux Fan Switch Failure?

Ok, so I just left for lunch and when I cranked my car, it made that sound again. I was able to check, and the aux fan wasn't even spinning. Bad motor? When I turn the AC on, the fan doesn't come on either.

Noise is the secondary air pump, pretty sure now from your description.
